To all whom it may concern:

Be it known that I, JosnrI-I C. KUEBLE'R, a citizen of the United States, residin at VJellsviile, Allegany county, New Yhrk, have invented certain new and useful limprovements in Processes and Apparatus for the Extracting of Oil from Wax, of wl rich tom thereof: 3, a valve-controlled outlet from the drainage gutter: 4, a second valvecontrolled outlet from the drainage gutter: 5, open grid-work near the bottom ,of the pan: 6, legs supporting the grid-work: 7, a horizontal screen lying on the grid-work: 8, cross bars lying on the screen: 9, a series of pipes disposed parallel with each other and extending lengthwise ot' the pan and resting on the cross bars: 10, a header-pipe connected with the heads of all of the. pipes: 11, a header connected with the tail ends of all of the pipes: 12, a transverse partition in header." 10, about midway of its length, whereby the header is divided into two chambers, one chamber communicating with about half of the pipes 9, while the other chamber communicates with the other half of tlfosc pipes: 13, an inlet pipe communi eating with one of the chambers of header 10 and adapted to convey, selectively, the cold water, hot Water or steam to header 10: 14, an outlet pipe from the other chamber of header 10: 15, water pipe adapted to deliver water into the pan: 16, a pipe adapted to deliver oil-bearing wax into the pan over the screen. 7

In the illustration header 10 is a single pipe provided with a transverse partition but it is obvious that the eflect is the same as would be the case if the two header chambers were formed of separate pipes. The construction causes the water or steam from pipe 13 to advance through one series of the pipes 9 and to return through the other In carrying out the improved process by the use 6r" this apparatus the steps are as follows :-Through the medium of pipe 15 cold water is delivered to the pan till the water stands somewhat above the top of the screen. Through the medium of pipe 16 the melted oil-bearing wax is then delivered into the pan over the water on which it floats, the quantity of wax admitted being sufiicient to nearly fill the shallow pan, or at least'to thoroughly cover pipes 9. Through the medium of pipe 13 cold water is now passed through the coils formed by the pipes 9, for congealing the floating wax and forming it into a cake. When the wax is sufiiciently solidified the water on which it is previously floated may be withdrawn through nipe 3, leaving the cake of wax supporter. above the screen by pipes 9 which are embedded in the wax. The cold water circulating through the pipes is now to be shut off and warm water passed through the pipes to greatly raise the temperature of the wax and cause the oil to sweat therefrom. The temperature of the warm water is to be raised as the sweating process proceeds, my practice being to begin to operate with the water at about deg. F. and end the process with the water at or near 130 deg. F. It is recommended that while the sweating process is going on under the in.- fluence of the heat thus applied to the interior of the cake of wax, the room temperature be correspondingly'raised.

In the earlystages of the sweating process the oil leaves the wax freely and as the wax becomes leaner in oil a higher temperature and a more prolonged subjection becomes necessary. The first drainage from thewax is free oil and this oil may be drained from the an as fast as it drains from the wax, or it desired it may be retained in the pan till the end of this stage at which point this free oil may be withdrawn from the pan in a body. After the tree oil has been sweated from the wax there will flow an oil carrying a percentage of wax, suflicient to congeal upon the fingers. This oil, known as yellow wax stock, may be drained from the pan as fast as it is sweated from the wax, or it may be held back in the pan and drained therefrom in a body. The next result of the sweating will be a liquid wax substantially free from oil and differs from the remaining wax mainly in having a lower melting temperature. It is termed light test wax and may be withdrawn it'ron'i the pan and taken care of separately The wax over the pipes is now in fibrous form, much similar in appearance to mineral wool. The warm water employed in the sweating process is now to be shut off and steam is to be passed through the pipes, thus melting down the fibrous mass of wax into-a liquid which is to be allowed to flow from the panto some receptacle where it may solidify into the prod- 'uct known as white wax.

I claim V 1. The improved process for separating oil and wax which consists of the following steps :first, depositing the oil-bearing wax in melted condition on a body of water and around a tube; second, passing a cooling medium through said tube to solidify the low the wax; fourth, passing a heating medium through the tube to raise the temperature of the wax sufliciently to sweat the oil from itspores; and fifth, passing a'heat ing medium through the tube to melt the wax from which the oil has been extracted, substantially as set forth.

2. Apparatus for separating oil and Wax comprising, an open toppedpan, an outlet therefrom, a horizontal screen supported in the pan, a series oi. tubes lying on the screen, pipes connected with the tubes to provide for a circulation therethrough of water and steam, a water inlet communicating with the pan, and a pipe for admitting melted 0il-bearing wax to the pan above the screen, combined substantially as set forth.
